5. Optimize Your Site's CSS
CSS, which is a code responsible for the style of the website, can slow down the loading speed of the page when it is not optimized. As a result, the waiting time of visitors increases and the possibility of them leaving the site increases. It can also pose a risk of being rated low by search engines. Optimizing CSS is very important in terms of improving the loading speed and performance of the web page. You can optimize your site's CSS by considering the following suggestions:

Reduce the use of special selectors and use global selectors more often, foruruguay mobile phone number example, use h1 instead of .header h1.
Reduce file size by keeping selectors short, for example, using .header-nav instead of .header-navigation.
Use caching on your CSS files.
If you are using multiple CSS files, combine them into one or more files and use them as a single file.
Remove spaces, line breaks, and comments from your CSS files to make them more compact.
By removing unnecessary font effects, you can reduce file size and increase loading speed.
6. Enable OPcache
OPcache is a caching system used to increase the speed of PHP applications. Enabling OPcache improves website performance and loading speed. It is very important to enable OPcache, especially for your workload-intensive website. Enabling OPcache reduces server resources, putting less load on the server, which allows for increased server performance.

Enabling OPcache is done on the server where the PHP application is running. You can enable OPcache by editing the PHP configuration file or using the web server administration panel.


7. Optimize Caching Issues
Caching is a technique used to store a previously loaded copy of a web page and quickly restore it for users who revisit that page. This technique contributes significantly to the speed at which pages load.

Sometimes caching issues can prevent pages from loading properly. This could be because the cached pages are out of date or some settings are not set correctly.
